The range extends from a single SIMD equipped HD 6300M through 6400M, 6500M, 6600M & 6700M, 6800M and 6900M.
All the GPU's are based on ATI's Terascale 2 technology, and some improved as seen in the 'Barts' architecture used for the Radeon HD 6800 series. All the chips support DirectX 11, OpenGL 4.1 and OpenCL 1.1, with the requisite drivers. UVD 3 support is a mixed bag; some have it, some don't. This is because the 6300M, 6500M and 6800M are rebrands of the Radeon Mobility HD 5400, 5700 and 5800.
The speeds and feeds bounce around a little, with the top of the range 6900M appearing very similar to a Radeon HD 6850 - once again, AMD are using their second tier desktop part as the top mobility part; no Mobility Cayman this time. Hopefully people won't be surprised by Radeon HD 6900M performance being so different from Radeon HD 6970 performance, despite the same numerical marketing number.

It doesn't seem likely that BluRay 3D will be much of a sticking point, as not many partners will equip their products with 120Hz screens for native support. However, if you were hoping to use your laptop as a sometime HTPC and play 3D BluRay's, you'll be out of luck unless you pick the right model with the right in it.
The rebranding appears to be part of AMD's ongoing strategy to fill in the gaps with new products, aligning their older products into more suitable markets and price points. However, this is being done, on the mobility side, at the expense of consistency and clarity.
Modern computer components lack severely in the 'name it what makes sense' classifications of marketing, with made up model numbers bearing no relation to real world aspects of performance, features or other aspect. Defining and maintaining at least some semblance of an relative performance index helps find a starting point for consumers looking at similar products at a particular price point.
AMD seem determined to make it as hard as possible to see what's what, as we've now got three new mobility GPU's with three rebranded ones, mixed in with new APU model numbers (HD 6200, HD 6300 for graphics) all launching at the same time. Add in the rest of the desktop consumer line up, from the Ultra high-end to the mainstream and value performance, we've got a lot of product to differentiate.
